This is a python interface to Adobe Font Metrics Files. Although a
number of other python implementations exist (and may be more complete
than mine) I decided not to go with them because either they were
either
1) copyrighted or used a non-BSD compatible license
2) had too many dependencies and I wanted a free standing lib
3) Did more than I needed and it was easier to write my own than
figure out how to just get what I needed from theirs
It is pretty easy to use, and requires only built-in python libs::
>>> from afm import AFM
>>> fh = file('ptmr8a.afm')
>>> afm = AFM(fh)
>>> afm.string_width_height('What the heck?')
(6220.0, 683)
>>> afm.get_fontname()
'Times-Roman'
>>> afm.get_kern_dist('A', 'f')
0
>>> afm.get_kern_dist('A', 'y')
-92.0
>>> afm.get_bbox_char('!')
[130, -9, 238, 676]
>>> afm.get_bbox_font()
